I bought a craftsman 24 cc weedwacker at the swap meet. Of course it doesn't run. It's missing the gas cap. Of the 2 fuel lines the long one has a bulb looking thing on the end in the tank, the other end goes through the tank and ends. the other connects to the carb, goes though the tank about 1/2" connects to a thing that looks like a filter and ends. there's nothing connected to the far end of the filter thing. the carb doesn't seem to have a float does it suck gas all the way from the tank?
